The SHP series is a revision to the FLY HopUp rubbers and is specifically designed for HPA systems. Due to the revised seal, the SHP series is also compatible with certain AEGs, a comparison can be found below in the description.
Patch: The patch on the SHP5 and rubber is identical to the FLY5 and has a radius of 2.5mm (5mm diameter). This is therefore smaller than the BB itself and thus ensures accurate centering of the BB in the barrel. Likewise, the BB is guided straight during firing to prevent runaway to the side. To generate a constant hop effect, the braking effect decreases in the front area.
Alignment: To prevent the bucking from twisting on the barrel, there are two supports in the inner area. These rest on the barrel and support the alignment and installation. This allows the installed tensioner to push the patch inside straight onto the BB, which also prevents runaway to the side. Note that a BB can only fly straight if the gun is also held straight.
Seal & Comparison: This is where the difference in the available HopUp rubbers lies. Especially with HPA systems, it often happens that the installed Nozzle can not be changed and is therefore not compatible with every rubber. This is where the SHP series comes into play.
-FLY rubbers have a slightly larger seal, making them compatible with flat nozzles. (e.g. many AEG nozzles). However, some manufacturers use a pointed Nozzle in their guns, if this is the case, the Nozzle had to be changed or adjusted in length. In the SHP series, the seal was made smaller, so now pointed nozzles no longer need to be changed.
Notice: For a flat or round Nozzle we still recommend the FLY series, for pointed Nozzles the SHP series should be used.
